UNITED STATES PATENT OFFICE.

LOUIS F. BERGMAN, OF NEW YORK, N. Y.

LAMP CHIMNEY OR GLOBE.

SPECIFICATION forming part of Letters Patent No. 7 58,955, dated May 3, 1904.

Application filed March 30, 1903- To all whom zit may concern.-

Be it known that I, LoUIs F. BERGMAN, a citizen of the United States. residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Lamp Chimneys or Globes, of which the following is a specification such as will enable those skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide an ordinary lamp chimney or globe one side of which is provided with a reflector whereby light of the lamp is always thrown in one'direction without the use of the supplemental or attached reflector.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a top view of one form of a lamp-chimney provided with my improvement, and Fig. 2 a section on the line 2 2 of Fig. 1.

In the practice of my invention, as shown in the drawings, I provide an ordinary cylindrical chimney f, in one side of which is formed a vertical recess g, which is segmental in cross-section and which extends downwardly almost to the bottom of the chimney,

as shown in Fig. 2, and this recess is filled Serial No. 150,125. (No model.)

It will be apparent that a lamp chimney or i globe of any desired form may be made in this manner and any part of such chimney or globe may thus be made to serve as a reflector.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

A lamp-chimney provided in one side with a recess which is open at the top and which contains fluid reflecting material, substantially as shown and described.

In testimony that I claim the foregoing a my invention I have signed my name, in presence of the subscribing witnesses, this 28th day of March, 1903.

LOUIS F. BERGMAN.
